It would be better to introduce a vaccination requirement for air travel than to keep enforcing masks. The only reason people have to wear masks is because we're letting unvaccinated people fly so the sensible people are footing the bill for the idiots (as usual in EU).
Many countries make me show a vaccination proof to enter a coffee bar or restaurant but when I confine myself in a compressed densely packed aluminum tube with 200 other people for hours there are suddenly no rules and we're wearing masks for take off and landing because the rest of the flight there is a cup of water standing in front of us to make sure we're having "a meal" to avoid the requirement.
